Can aluminum oxide be used with hydrogen peroxide in the dryers of air separation units?
I checked online; first of all, their crystal forms are different. Waiting for experts to reply
Yes, the crystal form is different, but you are taking advantage of the water-absorbing property of alumina; there’s no major issue, though the replacement cycle should be shorter
It cannot be used because the specific surface area is different; the specific surface area required for hydrogen peroxide is generally between 180 and 200, while that required for alumina used in air separation is above 280. When used for a short period of time in air separation, aluminum oxidized with hydrogen peroxide allows the system to operate, but its lifespan and water adsorption capacity are much lower. It will shorten the lifespan of the molecular sieve. Use with caution.
